2 Corinthians 10:8-11

Common(i) 8 For even if I boast somewhat further about our authority, which the Lord gave for building you up and not for destroying you, I shall not be put to shame. 9 I do not wish to seem as if I would terrify you by my letters. 10 For they say, "His letters are weighty and strong, but his personal presence is weak, and his speech of no account." 11 Let such people realize that what we are in our letters when we are absent, we will be in our actions when we are present.
